The gain or loss arising on the disposal of an asset is determined as the difference between the sale proceeds and the carrying value of the asset and is credited or charged to the profit or loss.
Impairment of fixed assets
At each reporting period end date, the company reviews the carrying amounts of its tangible and intangible assets to determine whether there is any indication that those assets have suffered an impairment loss. If any such indication exists, the recoverable amount of the asset is estimated in order to determine the extent of the impairment loss (if any).
Where it is not possible to estimate the recoverable amount on an individual asset, the company estimates the recoverable amount of the cash-generating unit to which the asset belongs.
Recoverable amount is the higher of fair value less costs to sell and value in use.
If the recoverable amount of an assets is estimated to be less than the carrying amount, the carrying amount of the asset is reduced to its recoverable amount. An impairment loss is recognised immediately in profit or loss.
